Houdini 19.0 Nodes VOP nodes

Filter Point Transforms VOP node

Find a point in an array and return the transforms in the corresponding arrays.

On this page
Since 18.5

This operator returns a set of transforms by looking up a given point, or sequence of points in an array and returning the corresponding entries from the given arrays of transforms.

This is useful when you wish to extract a transform for a point that has already be modified within the current VOP network, e.g. with a Get Descendant Transforms VOP.

Parameters

Signature

Default

Look up the point by index.

By Name

Look up the point by name.

Array

Look up multiple points given in an array of indices.

File

Specifies the input or operator location for the geometry file on which the queried point is found.

Geometry Path

Specifies the operator path that points to a SOP node.

This parameter is only available when File is set to Operator Path.

Point Number

Specifies an integer representing the point index to query.

Point Name

Specifies a string that represents the point name to query.

Group

A group string that expands to an array of points to query.

Inputs

file

A geometry file on which to query the attributes.

querypt

An integer representing the point index to query. By default, the first point index from the point group expansion is used.

pts

An array of points in which to search.

xforms

An array of world space transforms corresponding to the points given in pts.

localxforms

An array of local space transforms corresponding to the points given in pts.

efflocalxforms

An array of 'effective' local space transforms corresponding to the points given in pts.

Outputs

outfile

A pass through returning resolved File input or Geometry Path.

ptout

A point ID, or sequence of point IDs filtered from the pts input.

xform

A transform or sequence of transforms filtered from the xforms input.

localxform

A transform or sequence of transforms filtered from the localxforms input.

efflocalxform

A transform or sequence of transforms filtered from the efflocalxforms input.
